Physician groups are organizations made up of multiple doctors who work together to provide healthcare services. These groups can vary in size and may include specialists, primary care physicians, and other healthcare professionals. By collaborating, they can share resources, improve patient care, and streamline administrative tasks. These groups often operate under different models, such as independent practice associations or accountable care organizations. They may also negotiate contracts with insurance companies to ensure their services are covered. Overall, physician groups aim to enhance the quality of care while managing costs effectively.
